Abstract
BACKGROUND Microbiological diagnosis of intrauterine infections (IIU) still relies on bacteriological cultures or targeted DNA amplification lacking in sensitivity. Shotgun metagenomics (SMg) is an emerging unbiased molecular approach that makes it possible to sequence all the nucleic acids from any sample. It had never previously been used for IIU. METHODS We here report the case of a patient with an unexplained IIU and fetal loss that could be documented by a combined SMg/microbiological approach, leading to the diagnosis of maternal brucellosis. RESULTS A 31-year-old woman presented with an undocumented IIU with fetal loss at 24 weeks of gestation. Culture-based work-up failed to identify the pathogen involved. Paraffin-embedded placenta sample was retrospectively analyzed by SMg. Brucella spp nucleic acids were detected, and subacute maternal brucellosis was confirmed by targeted PCR and serological testing. CONCLUSION This case provides grounds for further utilization of SMg for the microbiological diagnosis of unexplained obstetrical infections.

Abstract
Infection by retroviruses as HIV-1 requires the stable integration of their genome into the host cells. This process needs the formation of integrase (IN)-viral DNA complexes, called intasomes, and their interaction with the target DNA wrapped around nucleosomes within cell chromatin. To provide new tools to analyze this association and select drugs, we applied the AlphaLISA technology to the complex formed between the prototype foamy virus (PFV) intasome and nucleosome reconstituted on 601 Widom sequence. This system allowed us to monitor the association between both partners and select small molecules that could modulate the intasome/nucleosome association. Using this approach, drugs acting either on the DNA topology within the nucleosome or on the IN/histone tail interactions have been selected. Within these compounds, doxorubicin and histone binders calixarenes were characterized using biochemical, in silico molecular simulations and cellular approaches. These drugs were shown to inhibit both PFV and HIV-1 integration in vitro. Treatment of HIV-1-infected PBMCs with the selected molecules induces a decrease in viral infectivity and blocks the integration process. Thus, in addition to providing new information about intasome-nucleosome interaction determinants, our work also paves the way for further unedited antiviral strategies that target the final step of intasome/chromatin anchoring. IMPORTANCE In this work, we report the first monitoring of retroviral intasome/nucleosome interaction by AlphaLISA. This is the first description of the AlphaLISA application for large nucleoprotein complexes (>200 kDa) proving that this technology is suitable for molecular characterization and bimolecular inhibitor screening assays using such large complexes. Using this system, we have identified new drugs disrupting or preventing the intasome/nucleosome complex and inhibiting HIV-1 integration both in vitro and in infected cells. This first monitoring of the retroviral/intasome complex should allow the development of multiple applications including the analyses of the influence of cellular partners, the study of additional retroviral intasomes, and the determination of specific interfaces. Our work also provides the technical bases for the screening of larger libraries of drugs targeting specifically these functional nucleoprotein complexes, or additional nucleosome-partner complexes, as well as for their characterization.

Abstract
Sepsis is a severe affection, that requires an urgent and specific treatment sequence. Physiological changes occurring during pregnancy make the diagnosis of sepsis more challenging in this setting, with possible delay in treatment initiation, that in turn is responsible for poorer maternal and fetal outcome. This review aims to summarize current knowledge on the diagnosis and treatment of maternal sepsis, as well as persistent knowledge gaps in the field.

Abstract
We herein report two cases of cathinone intoxication. The first case is about a drug addict who was admitted to the emergency room after the injection of an unknown compound. He presented with tachycardia, palpitations, mydriasis, dyspnea, dizziness, headache and nausea. After leaving the hospital against medical advice, he returned the next day with police escort, presenting aggressiveness and agitation signs. One month later, he returned one more time for sleeping disorders, hallucinations and anxiety. He was finally transferred for his 21st detoxification treatment. The second case concerns a man who was wandering the streets and tried to escape when police officers called him. He confessed to snorting of N-ethylpentedrone and was admitted with severe agitation including delusion of persecution, tachycardia, mydriasis and fever. Because of renal failure, rhabdomyolysis and metabolic acidosis, he was transferred to the intensive care unit where he manifested worsening of the symptoms, turning into coma. He was intubated for 3 days before a complete resolution of the symptoms. A screening was performed by high-resolution mass spectrometry followed by quantifications made by high-performance liquid chromatography coupled with a diode array detector. In the first case, alpha-pyrrolidinohexiophenone was identified only during the first two admissions. However, as plenty of other psychotropic substances were also found, the cathinone alone could not be held directly responsible for the symptoms. In the second case, more than 2,000 ng/mL of N-ethylpentedrone was found without any decrease in the next 17 h, underlining the long half-life of this compound. Unlike the first case, symptoms could be clearly attributed to the cathinone. In conclusion, cathinones can be found on the Belgian illicit drug market, with various routes of administration and clinical consequences. In these two case reports, some common points were observed initially. However, one patient was finally able to leave the hospital without any treatment, whereas the other would most likely have died without intensive care.

Abstract
Background Meiotic recombination plays an important role in reproduction and evolution. The individual global recombination rate (GRR), measured as the number of crossovers (CO) per gametes, is a complex trait that has been shown to be heritable. The sex chromosomes play an important role in reproduction and fertility related traits. Therefore, variants present on the X-chromosome might have a high contribution to the genetic variation of GRR that is related to meiosis and to reproduction. Results We herein used genotyping data from 58,474 New Zealand dairy cattle to estimate the contribution of the X-chromosome to male and female GRR levels. Based on the pedigree-based relationships, we first estimated that the X-chromosome accounted for 30% of the total additive genetic variance for male GRR. This percentage was equal to 19.9% when the estimation relied on a SNP-BLUP approach assuming each SNP has a small contribution. We then carried out a haplotype-based association study to map X-linked QTL, and subsequently fine-mapped the identified QTL with imputed sequence variants. With this approach we identified three QTL with large effect accounting for 7.7% of the additive genetic variance of male GRR. The associated effects were equal to + 0.79, − 1.16 and + 1.18 CO for the alternate alleles. In females, the estimated contribution of the X-chromosome to GRR was null and no significant association with X-linked loci was found. Interestingly, two of the male GRR QTL were associated with candidate genes preferentially expressed in testis, in agreement with a male-specific effect. Finally, the most significant QTL was associated with PPP4R3C, further supporting the important role of protein phosphatase in double-strand break repair by homologous recombination. Conclusions Our study illustrates the important role the X-chromosome can have on traits such as individual recombination rate, associated with testis in males. We also show that contribution of the X-chromosome to such a trait might be sex dependent.

Abstract
INTRODUCTION Needle aspiration of breast abscesses during lactation are currently recommended as an alternative to surgery only for moderate forms. In case of breast abscess, many patients stop breastfeeding on the advice of a health professional. We reviewed our experience of treatment of lactating breast abscesses by ultrasound-guided aspiration and suggest an algorithm of their management. We also analyzed the continuation of breastfeeding of these patients after advices from trained teams. MATERIEL AND METHODS We conducted a retrospective study from April 2016 to April 2017, including 28 patients referred for a breast abscess during lactation at the Duroc Breast Imaging Center. A management by ultrasound-guided aspiration was proposed to each patient. We collected data about the breastfeeding between October 2018 and January 2019. RESULTS A single aspiration was sufficient in 64.3% of cases. The delay between the occurrence of the abscess and the indication for drainage was significantly higher for patients who have needed finally surgical drainage (p = 0,0031). There were no difference of size of abscesses between patients receiving needle aspiration alone and those who have undergone surgery (p = 0,97). All patients who had been managed by needle aspiration continued breastfeeding after the treatment and 40% of the patients were still breastfeeding at 6 months. CONCLUSION The management of lactating breast abscess by ultrasound-guided needle aspiration is an effective alternative to surgery. It appears to be effective regardless of the size of the abscess and is compatible with the continuation of breastfeeding. Our study has indeed shown that if they are well advised, the majority of patients continue breastfeeding so that it is essential that health professionals be better trained regarding the management of breastfeeding complications.

Abstract
The occurrence of metabolic acidosis with increased anion gap in the context of chronic paracetamol intoxication is an easily treatable clinical situation. Its rapid recognition is essential given its complete reversibility in the event of adequate management by eviction of the toxic agent, in this case paracetamol. It has an unknown cause and therefore potentially under-diagnosed, to be considered in the same way as the other more frequent etiologies. Because of this lack of knowledge, its frequency is probably underestimated considering the widespread consumption of paracetamol in the population.

Abstract
Endocrine disruptors are chemicals or natural molecules able to interfere with the hormonal system of living organisms. These pollutants can promote the emergence of diseases of the endocrine system in humans or animals. In this publication, we will focus on certain families of endocrine disrupting chemicals that may contribute to the development of type 2 diabetes, a disease whose prevalence is increasing strongly in the world.

Abstract
Abstract
Background
The arrival of highly effective, well-tolerated, direct-acting antiviral agents (DAA) led to a dramatic decrease in hepatitis C virus (HCV) prevalence. Human immunodeficiency virus (HIV)-HCV–coinfected patients are deemed a priority population for HCV elimination, while a rise in recently acquired HCV infections in men who have sex with men (MSM) has been described. We describe the variations in HIV-HCV epidemiology in the French Dat’AIDS cohort.
Methods
This was a retrospective analysis of a prospective cohort of persons living with HIV (PLWH) from 2012 to 2018. We determined HCV prevalence, HCV incidence, proportion of viremic patients, treatment uptake, and mortality rate in the full cohort and by HIV risk factors.
Results
From 2012 to 2018, 50 861 PLWH with a known HCV status were followed up. During the period, HCV prevalence decreased from 15.4% to 13.5%. HCV prevalence among new HIV cases increased from 1.9% to 3.5% in MSM but remained stable in other groups. Recently acquired HCV incidence increased from 0.36/100 person-years to 1.25/100 person-years in MSM. The proportion of viremic patients decreased from 67.0% to 8.9%. MSM became the first group of viremic patients in 2018 (37.9%). Recently acquired hepatitis represented 59.2% of viremic MSM in 2018. DAA treatment uptake increased from 11.4% to 61.5%. More treatments were initiated in MSM in 2018 (41.2%) than in intravenous drug users (35.6%). In MSM, treatment at the acute phase represented 30.0% of treatments in 2018.
Conclusions
A major shift in HCV epidemiology was observed in PLWH in France from 2012 to 2018, leading to a unique situation in which the major group of HCV transmission in 2018 was MSM.

Abstract
We study a one-parameter family of probability measures on lozenge tilings of large regular hexagons that interpolates between the uniform measure on all possible tilings and a particular fully frozen tiling. The description of the asymptotic behavior can be separated into two regimes: the low and the high temperature regime. Our main results are the computations of the disordered regions in both regimes and the limiting densities of the different lozenges there. For low temperatures, the disordered region consists of two disjoint ellipses. In the high temperature regime the two ellipses merge into a single simply connected region. At the transition from the low to the high temperature a tacnode appears. The key to our asymptotic study is a recent approach introduced by Duits and Kuijlaars providing a double integral representation for the correlation kernel. One of the factors in the integrand is the Christoffel-Darboux kernel associated to polynomials that satisfy non-Hermitian orthogonality relations with respect to a complex-valued weight on a contour in the complex plane. We compute the asymptotic behavior of these orthogonal polynomials and the Christoffel-Darboux kernel by means of a Riemann-Hilbert analysis. After substituting the resulting asymptotic formulas into the double integral we prove our main results by classical steepest descent arguments.

Abstract
OBJECTIVE Perfluoroalkyl substances (PFAS) are chemicals widely employed in the industry. Long term consequences of the newborns' contamination by PFAS on thyroid function are of concern. The aim of this study is to assess the potential associations between PFAS contamination measured at birth and thyroid function assessed few months later. PFAS levels were previously determined in cord blood from a cohort of newborns recruited in Liege. METHOD Parents of the children belonging to the first and the fifth quintiles of exposure to PFAS were contacted in order to measure the thyroid stimulating hormone (TSH) levels in their child few months after birth. Twenty-eight children participated in the study. Moreover, we performed a literature review about associations between pre- or perinatal exposure to persistent organic pollutants and thyroid function during early childhood. RESULT No significant difference was highlighted between both groups of contamination (Mann-Whitney, p-value = 0.91). Literature review highlighted the critical need of new longitudinal data about this problematic. CONCLUSION Our results suggest that the PFAS levels at birth are not associated with TSH levels later in life. Large scale studies are required to confirm our results.

Abstract
Congenital syphilis (CS) is caused by Treponema pallidum infection in utero. There is a need to develop new tools to diagnose CS: the diagnostic value of PCR is difficult to assess. The aim of this study was to describe the clinical and laboratory characteristics of mothers and infants with CS as diagnosed by PCR tests on various maternal and neonatal samples. PATIENTS AND METHODS We included all infants epidemiologically linked to a mother diagnosed with syphilis whose samples were referred to the Syphilis Reference Center, and for whom at least one positive PCR result was obtained. RESULTS Twenty-two mother-infant pairs (8.3%) with assay performed on samples from one to four different anatomic sites were included between February 2011 and April 2018. Seven mothers (31.8%) were born abroad, fifteen (68.2%) presented psychological and/or social problems, eight (36.4%) had not been screened for syphilis prior to delivery, and eleven (50%) were referred from French overseas departments or territories, or from the Paris region. Six infants (27.3%) were stillborn and six were born preterm, while fifteen infants (68.2%) presented clinical features of CS. All infants born preterm were symptomatic. Infant VDRL/RPR titer was no greater than four times that in the mother's serum, except in two cases. DISCUSSION Lack of antenatal care, social disadvantage and psychological issues were common. There is a need for enhanced surveillance both in the French overseas departments/territories and in the Paris region. A larger study is required to assess the sensitivity and specificity of PCR. The best site for sampling has yet to be established. We recommend the collection of as many samples as possible to avoid underdiagnosis of CS.

Abstract
To recognize an alcoholic subject is a frequent request, in a medical or forensic setting. The reasons to determine the alcoholic status of an individual are many and various. Amongst the most frequent are : to decide on the origin of liver or neurological disease, put and maintain a liver transplantation candidate on a waiting list, identify the alcoholic worker to prevent work-related accidents, or evaluate the possible risk an alcoholic individual represents, for road safety or for parental custody. The specific alcohol consumption biological markers combined with clinical and psychological examinations are the best tools to identify the individuals with a problematic consumption. The use of markers belongs to the recommended actions to support patients undergoing treatment for alcoholism. It is mandatory in various situations to distinguish between the teetotaler, the moderate or problematic drinkers. Different biomarkers are described here to allow practitioners to adapt their prescriptions.

Abstract
OBJECTIVE To determine management of women with preterm premature rupture of membranes (PPROM). METHODS Bibliographic search from the Medline and Cochrane Library databases and review of international clinical practice guidelines. RESULTS In France, PPROM rate is 2 to 3% before 37 weeks of gestation (level of evidence [LE] 2) and less than 1% before 34 weeks of gestation (LE2). Prematurity and intra-uterine infection are the two major complications of PPROM (LE2). Compared to other causes of prematurity, PPROM is not associated with an increased risk of neonatal mortality and morbidity, except in case of intra-uterine infection, which is associated with an augmentation of early-onset neonatal sepsis (LE2) and of necrotizing enterocolitis (LE2). PPROM diagnosis is mainly clinical (professional consensus). In doubtful cases, detection of IGFBP-1 or PAMG-1 is recommended (professional consensus). Hospitalization of women with PPROM is recommended (professional consensus). There is no sufficient evidence to recommend or not recommend tocolysis (grade C). If a tocolysis should be prescribed, it should not last more than 48hours (grade C). Antenatal corticosteroids before 34 weeks of gestation (grade A) and magnesium sulfate before 32 weeks of gestation (grade A) are recommended. Antibiotic prophylaxis is recommended (grade A) because it is associated with a reduction of neonatal mortality and morbidity (LE1). Amoxicillin, 3rd generation cephalosporins, and erythromycin in monotherapy or the association erythromycin-amoxicillin can be used (professional consensus), for 7 days (grade C). However, in case of negative vaginal culture, early cessation of antibiotic prophylaxis might be acceptable (professional consensus). Co-amoxiclav, aminosides, glycopetides, first and second generation cephalosporins, clindamycin, and metronidazole are not recommended for antibiotic prophylaxis (professional consensus). Outpatient management of women with clinically stable PPROM after 48hours of hospitalization is a possible (professional consensus). During monitoring, it is recommended to identify the clinical and biological elements suggesting intra-uterine infection (professional consensus). However, it not possible to make recommendation regarding the frequency of this monitoring. In case of isolated elevated C-reactive protein, leukocytosis, or positive vaginal culture in an asymptomatic patient, it is not recommended to systematically prescribe antibiotics (professional consensus). In case of intra-uterine infection, it is recommended to immediately administer an antibiotic therapy associating beta-lactamine and aminoside (grade B), intravenously (grade B), and to deliver the baby (grade A). Cesarean delivery should be performed according to the usual obstetrical indications (professional consensus). Expectative management is recommended before 37 weeks of gestation in case of uncomplicated PPROM (grade A), even in case of positive vaginal culture for B Streptococcus, provided that an antibiotic prophylaxis has been prescribed (professional consensus). Oxytocin and prostaglandins are two possible options to induce labor in case of PPROM (professional consensus). CONCLUSION Expectative management is recommended before 37 weeks of gestation in case of uncomplicated PPROM (grade A).

Abstract
OBJECTIVE To determine the diagnosis criteria and management of intra-uterine inflammation or infection (Triple I, III). METHODS PubMed and Cochrane Central databases search. RESULTS III is defined as an infection of the fetal membranes, and/or other components like the decidua, fetus, amniotic fluid or placenta. This word should be preferred to the word chorioamnionitis that is less precise (Professional consensus). III clinical signs exhibit poor limited sensibility and specificity (EL3). The diagnosis of III is retained in case of maternal fever (defined by a body temperature≥38°C) with no alternative cause identified and at least 2 signs among the following: fetal tachycardia>160 bpm for 10min or longer, uterine pain of labor, purulent fluid from the cervical canal (Professional consensus). Maternal hyperleukocytosis>20 giga/L in the absence of corticosteroids treatment or increased plasmatic C-reactive protein also argue for III, despite their limited sensibility and specificity (EL3). III requires prompt delivery (Grade A). III is not by itself an indication for cesarean delivery (Professional consensus). Antibiotic treatment should cover Streptococcus agalactiae and Escherichia coli. Antibiotics should be started immediately and maintained all over delivery, to reduce neonatal and maternal morbidity (Grade B). Treatment should rely on a combination of betalactamin and aminoglycoside (Grade B). After vaginal delivery, one single dose of antibiotic is required. Antibiotic duration should be longer in case of bacteremia. Longer duration could be considered in case of persistent fever or of cesarean delivery (Professional consensus).

Abstract
OBJECTIVES Listeria monocytogenes (Lm) is a foodborne human pathogen responsible for severe infections, including septicaemia, neurolisteriosis, and maternal-foetal and focal infections. Little is known about Lm-associated respiratory tract or lung infections. METHODS We conducted a retrospective study of culture-proven cases of Lm pleural infections and pneumonia reported to the French National Reference Centre for Listeria from January 1993 to August 2016. RESULTS Thirty-eight consecutive patients with pleural infection (n = 32), pneumonia (n = 5), or both (n = 1) were studied; 71% of these were men. Median age was 72 (range 29-90). Two patients presented with concomitant neurolisteriosis. All patients but one reported at least one immunosuppressive condition (97%), with a median number of 2 (range 0-5), including 29% (8/28) with current exposure to immunosuppressive therapy and 50% (17/34) with ongoing neoplasia; 75% (21/28) reported previous pleural or pulmonary disease. Antibiotic therapy mostly consisted in amoxicillin (72%) associated with aminoglycoside in 32%. Chest-tube drainage was performed in 7/19 patients with empyema (37%); 25% of the patients (7/30) required intensive care management. In-hospital mortality reached 35% and occurred after a median time interval of 4 days (range 1-33 days). Three patients had recurrence of empyema (time interval of 1 week to 4 months after treatment completion). Altogether, only 13/31 patients (42%) diagnosed with Lm respiratory infection experienced an uneventful outcome at 2-year follow-up. CONCLUSION Lm is a rare but severe cause of pneumonia and pleural infection in older immunocompromised patients, requiring prompt diagnosis and adequate management and follow-up.

Abstract
In-cell NMR of macromolecules has gained momentum over the last ten years as an approach that might bridge the branches of cell biology and structural biology. In this review, we put it in the context of earlier efforts that aimed to characterize by NMR the cellular environment of live cells and their intracellular metabolites. Although technical aspects distinguish these earlier in vivo NMR studies and the more recent in cell NMR efforts to characterize macromolecules in a cellular environment, we believe that both share major concerns ranging from sensitivity and line broadening to cell viability. Approaches to overcome the limitations in one subfield thereby can serve the other one and vice versa. The relevance in biomedical sciences might stretch from the direct following of drug metabolism in the cell to the observation of target binding, and thereby encompasses in-cell NMR both of metabolites and macromolecules. We underline the efforts of the field to move to novel biological insights by some selected examples.

Abstract
OBJECTIVES Direct-Acting Antivirals (DAAs) opened a new era in HCV treatment. We report the impact of HCV treatment in French HIV-HCV coinfected patients. METHODS All HIV-HCV patients from the Dat'AIDS cohort followed between 2012 and 2015 were included. HCV status was defined yearly as naive, spontaneous cure, sustained virological response (SVR12), failure or reinfection. RESULTS Among 32,945 HIV-infected patients, 15.2% were positive for anti-HCV antibodies. From 2012 to 2015, HCV incidence rate increased from 0.35%PY to 0.69%PY in MSM, while median incidence was 0.08%PY in other patients. Median reinfection rate was 2.56%PY in MSM and 0.22%PY in other patients. HCV treatment initiation rate rose from 8.2% in 2012 to 29.6% (48.0% in pre-treated patients vs 22.6% in naïve patients). SVR12 rate increased from 68.7% to 95.2%. By the end of 2015, 62.7% of the patients were cured either spontaneously or following SVR. CONCLUSIONS HCV treatment dramatically increased in HIV-HCV patients in France from 2012 to 2015 resulting in HCV cure in nearly two-thirds of the patients in this cohort. Combined with a declining HCV prevalence, the prevalence of active HCV infection among HIV patients will drastically decrease in the forthcoming years.

Abstract
Electronic cigarettes (e-cigarettes) are presented as a healthier alternative to tobacco smoking. They are designed to contain a solution which is heated to produce an aerosol inhaled by the user. The liquid is mainly composed of propylene glycol, glycerol, flavours and, in some cases, nicotine. Except for nicotine, which can be fatal when ingested at high dose, these components are generally considered as safe. However, the potential effect of long term exposure to inhaled propylene glycol is unknown at this time. As an advantage, toxic compounds responsible for the noxiousness of tobacco smoking (nitrosamines, metals, formaldehyde, carbon monoxide …) are either absent, or present in the smoke of e-cigarette at levels far less compared to conventional cigarette smoke. Finally, efficacy of e-cigarette as a tool for smoking cessation stays to be proven.

Abstract
Exposure to heavy metals is a common phenomenon due to their prevalence in food and environment; their toxicity remains a major concern for public health. Chelating agents are drugs used to increase the elimination of metals present at abnormally high levels in the body. Their approved clinical indications are limited, particularly because of their potential adverse effects. Unfortunately, too often, chelating agents are used to test the body impregnation level by heavy metals. It is an inappropriate and abusive use. In order to attract attention to this problematic, the good and bad uses of metal chelators are reviewed.

Abstract
OBJECTIVES In Rwanda, no therapeutic monitoring of psychotropic drugs is done. This results in difficult treatment optimisation and exposition to a high risk of toxicity and drug ineffectiveness for patients under treatment. This study aimed to determine blood concentration levels of psychotropic drugs in Rwandan patients and identify problems associated with the lack of therapeutic drug monitoring (TDM) of these drugs. METHODS The analysis was performed on 1 ml of serum sample using prazepam as internal standard. Regarding the step of sample preparation, we used a liquid-liquid extraction with a mixture of organic solvents: diethyl ether/dichloromethane/hexane/n-amyl alcohol (50/30/20/0.5:V/V). A Waters Alliance 2695 was used for analysis. The chromatography was run on a Symmetry C8 column and as mobile phase acetonitrile and phosphate buffer (pH 3.8) were used. RESULTS Concerning the results, serum samples from 128 patients were analysed. Twenty-one different psychotropic drugs belonging to various pharmacological classes were detected and quantified. Analytical results were put into three categories based upon therapeutic reference ranges (TRR) of various drugs: subtherapeutic, therapeutic and supratherapeutic. For a total of 237 analyses, results within TRR represented 46% while 47 and 8% of results were, respectively, below and above TRR. CONCLUSION It was therefore concluded that patients under psychotropic treatment in Rwanda are exposed to both the risk of drug ineffectiveness and the risk of toxicity (54%) with only 46% of results within the TRR. Consequently, TDM is needed to optimise psychotropic treatment in Rwandan patients.

Abstract
OBJECTIVES The objective of the study was to describe 'the results of the blood alcohol determinations made on drivers from the Liege area between 2007 and 2012. METHODS The results were interpreted according to the sex, to the age, to the circumstances and temporal variation of the test. Statistical analysis was performed using R® software. RESULTS 2725 determinations were done, mainly after crashes. The mean blood alcohol concentration (BAC) was 1.69 g/L, and 2132 drivers were above the legal threshold. A majority of offenders were men, but the mean BAC did not differ significantly between men and women. A correlation between age and mean BAC can be observed on the positive cases. Lowest and highest mean BACs are observed during the daytime and during the night, respectively, but no significant difference can be observed between the week and the weekend. Finally, no significant difference in BAC was observed over years.

Abstract
All methadone-associated deaths from October 2002 to April 2005 are analysed. A regular increase in these fatal intoxications has been recorded, in Belgium as in other countries, due, in particular, to an intensified prescription of this product, of which illicit use as street dope becomes problematic. Over the 30 months period covered by the study, 26 deaths related to methadone were listed, of which 3 occurred in accidental circumstances. In the other 23 cases, methadone can be found, yet always associated with psychotropic substances, mainly benzodiazepines (18 cases), narcotics (15 cases) and finally alcohol (5 cases). Based upon the nature of the products combined with methadone, records have been divided in two groups: In the first group (17 observations), xenobiotics at (infra)therapeutic levels are detected. In the other group (6 observations), xenobiotics at high and toxic levels are detected. Blood methadone concentrations are not so different between the 2 groups of individuals since the median values and the extreme values are worth respectively 308, and 110-11300 microg/L, for the first group and 776 and 93-2080 microg/L for the second group. There is thus an important overlap between the therapeutic blood methadone concentrations (150-400 microg/L) and blood concentrations observed in fatalities.Thus, it is necessary that all information and post-mortem results must be examined in a critical way to identify and justify cause of the death.

Abstract
Xenoestrogens such organochlorine pesticides are known to induce changes in reproductive development, function or behaviour in wildlife. Because these compounds are able to modify the estrogens metabolism, or to compete with estradiol for binding to the estrogen receptor, it may be possible that these products affect the risk of developing impaired fertility, precocious puberty or some kinds of cancer in man. Le plus ancien récit de lutte contre la pollution remonte à une légende indienne racontant que la divinité Sing-bonga était incommodée par les émanations des fours dans lesquels les Asuras fondaient leurs métaux (1). Evidemment depuis, la problématique n-a cessé de s-accroître et la contamination de la Terre par de nombreux polluants est devenue aujourd-hui un problème majeur de notre Société. La protection de notre environnement est une question capitale qui doit être respectée malgré la pression économique actuelle et qui ne cessera de croître au cours des prochaines années même si l-identification objective et indiscutable de ce qui est essentiel - donc devant être prioritairement garanti sur la planète - est difficile à cerner (2). « Un oiseau en mauvais état ne pond pas de bons oeufs » disait un proverbe grec. Mais ce n-est qu-à partir de la seconde moitié du XXème siècle que les toxicologues ont commencé à identifier les effets qu-avaient entraînés à l-échelle mondiale les pollutions émises aux XIXème siècle sur la faune sauvage et sur le cheptel (3). L-histoire contemporaine des pesticides industriels commence vers 1874 (synthèse des organochlorés) et se poursuit tout au long de ces 2 siècles en passant par la synthèse des organophosphorés (1950), des carbamates (1970) et des pyréthroïdes (1975) (4). Le dichlorodiphényltrichloroéthane (DDT) a été synthétisé pour la première fois par un étudiant en cours de préparation de sa thèse de doctorat : Othmer Zeidler. La production, reprise par les entreprises F.Mayo puis par la Geigy Co. a d-abord intéressé l-armée, puis l-agriculture. Dès la fin de la 2(ème) guerre mondiale, des mises en garde furent lancées à propos des effets nocifs du produit (4). Un déclin des populations de grives, d-aigles chauves, d-orfaies et de mammifères consommateurs de poissons fut constaté à partir des années 50 et dénoncé par Rachel Carson dans son célèbre appel du « Silent Spring » de 1962. Bien qu-il soit interdit en Occident depuis les années 70, ce produit a été tellement utilisé et présente une rémanence si longue qu-une contamination ubiquitaire existe aujourd-hui encore. De plus, ce produit continue à être produit aux USA pour être utilisé à des fins de démoustification dans les pays en voie de développement. Il en va de même de l-Hexachlorobenzène (HCB), un autre organochloré dont l-usage est interdit sous nos latitudes, mais reste fréquent dans d-autres pays. Ces deux exemples indiquent que le problème de la contamination continue à nous concerner, même pour des produits dont l-usage est aujourd-hui strictement réglementé ou interdit. Des effets sur la faune semblent encore actuellement devoir être attribués à ces produits. La diminution de la population des phoques dans la mer de Wadden pourrait être due à la forte contamination en composants organochlorés des poissons dont ces phoques se nourrissent (5). Exposé au DDT et à son métabolite dichlorodiphenyldichloroéthylène (DDE), le Seratherodon mossambicus présente une réduction de la sécrétion de cortisol par une action toxique cytospécifique sur l-axe hypothalamo-hypophysaire (6). Des travaux récents ont montré que le DDT et le DDE se lient chez les oiseaux et les mammifères au moyen de liaisons covalentes aux cellules de la zona fasciculata - homologue du tissu interrénal du poisson - induisant des microhémorragies. Cette « défaillance » cortisolique peut s-accompagner d-une perturbation du métabolisme glucidique et notamment d-un taux élevé de glycogène hépatique (7). Les pesticides organochlorés (DDT, DDE) entraînent également des perturbations d-ordre métabolique chez certaines espèces d-oiseaux, notamment le faucon pèlerin en Grande Bretagne et les oiseaux piscivores des grands lacs nord américains où l-on a constaté au cours des années 1960 que leur reproduction était menacée et qu-une des manifestations les plus évidentes des perturbations observées était le taux élevé de malformations (8). Des mortalités élevées de poissons ou de coquillages ont été rapportées dans des élevages situés à proximité des zones d-épandage de pesticides organophosphorés et de carbamates. En 1991, la dispersion aérienne de fenitrothion dans le but de provoquer la démoustication en Languedoc a été à l-origine de la perte de plusieurs tonnes de crevettes japonaises. L-utilisation de trichlorfon et de dichlorvos comme antiparasitaires dans des fermes d-élevages de saumons a provoqué des épisodes de mortalité importante (9).

Abstract
Azole antifungals are a group of fungistatic agents that can be administered orally or parenterally. The determination of the concentrations of these antifungals (miconazole, fluconazole, ketoconazole, posaconazole, voriconazole, itraconazole, and its major active metabolite, hydroxy-itraconazole) in serum can be useful to adapt the doses to pharmacological ranges because of large variability in the absorption and metabolism of the drugs, multiple drug interactions, but also potential resistance or toxicity. A method was developed and validated for the simultaneous determination of these drugs in serum utilizing ultra-high pressure liquid chromatography and diode array detection (UHPLC-DAD). After a simple and rapid liquid-liquid extraction, the pre-treated sample was analysed on an UHPLC-DAD system (Waters Corporation(®)). The chromatographic separation was carried out on an Acquity BEH C18 column (Waters Corporation) with a gradient mode of mobile phase composed of acetonitrile and aqueous ammonium bicarbonate 10·0 M pH10. The flow rate was 0·4 ml/min and the injection volume was 5 μl. The identification wavelength varied according to the drug from 210 to 260 nm. The method was validated by the total error method approach by using an analytical validation software (e•noval V3·0 Arlenda(®)). The seven azole antifungals were identified by retention time and specific UV spectra, over a 13-minute run time. All calibration curves showed good linearity (r(2)>0·99) in ranges considered clinically adequate. The assay was linear from 0·05 to 10 mg/l for voriconazole, posaconazole, itraconazole, hydroxy-itraconazole, and ketoconazole, from 0·3 to 10 mg/l for fluconazole, and from 0·1 to 10 mg/l for miconazole. The bias and imprecision values for intra- and inter-assays were lower than 10% and than 15%, respectively. In conclusion, a simple, sensitive, and selective UHPLC-DAD method was developed and validated to determine seven azole antifungal drugs in human serum. This method is applicable to patient samples, and can be applied successfully to clinical applications and therapeutic drug monitoring.
